Increase Wifi Signal Strength Tx-Power on Kali Linux

This week I just learn and try the new wi-fi device, and of course also testing their durability (maximize the warranty time 😛 ). Today we will learn together how to Increase Wifi Signal Strength Tx-Power on Kali Linux, actually you can do this on other Linux distro as well, but in this article we will do on a Kali Linux.

The default Tx-Power of wireless is set to 20 dBm or 100 mW, usually used by 802.11b/g Wireless LAN 20 MHz-wide channels in the 2.4 GHz ISM band (5 mW/MHz) and bluetooth Class 1 radio.

We also able to set the Tx-power default setting from 20 dBm = 100mW increased to 30 dBm or 1 W = 1000mW, but we must do this with our own risk as it will probably damage your card eventually! Moreover increase the tx-power can be illegal in some countries, so it’s better you find out your country rule of law.
